As of July 2, Neal said he had no choice but to file suit in federal court in order to compel the Internal Revenue Service to turn over the records.

“In refusing to comply with the statute, Defendants have mounted an extraordinary attack on the authority of Congress to obtain information needed to conduct oversight of Treasury, the IRS, and the tax laws on behalf of the American people,” the lawsuit (Case No. 1:19-cv-1974)—filed against the U.S. Department of the Treasury, the Internal Revenue Service, Steven T. Mnuchin, and IRS Commissioner Charles P. Rettig in the U.S. District Court for the District of Columbia— says.

According to a report by Politico, Trump lawyer Jay Sekulow had a terse response to the suit.

“We will respond to this latest effort at presidential harassment in court,” he said.

And that may be sooner than he thinks: While the fight over Trump’s taxes could be lengthy, with the administration likely to try to drag out the proceedings beyond next year’s elections, Politico said that “some see signs the courts are trying to move quickly on the oversight challenges.”

“They’re not unaware the administration is throwing up roadblocks at every conceivable opportunity and I think they understand that the system itself is under stress,” Kerry Kircher, who was the House’s general counsel from 2011 to 2016 and deputy counsel from 1996 to 2010, told the political news outlet, adding, “The judiciary is aware of the need for some expedition here, and that we can’t go through the usual processes where it takes a couple years for these cases to work themselves out.”

Neal asked the court for a speedy decision, reminding it that sessions of Congress only run two years.

“If this Court does not redress Defendants’ noncompliance quickly, the Committee will be unable to fulfill its essential role of overseeing the Executive Branch or to carry out its constitutional obligation to legislate,” the suit says.
